[0079] Comparative Example 1.

[0080] The difference from Example 3 is that chitosan was not added to adjust the yttrium oxide modifier.

[0081] Comparative Example 2.

[0082] Different from Example 3, yttrium oxide is used instead of pre-modified yttrium oxide in the preparation of chitosan-regulated yttrium oxide modifier.

[0083] Comparative Example 3.

[0084] Different from Example 3, the chitosan compounding agent in the preparation of chitosan-regulated yttrium oxide modifier does not add a compounding agent.

[0085] Comparative Example 4.

[0086] Different from Example 3, lanthanum nitrate solution is not added in the preparation of the compounding agent.

[0087] Comparative Example 5.

[0088] Different from Example 3, the whisker-modified compounding agent is not added.

[0089] Comparative Example 6.

[0090] Different from Example 3, aluminum borate whiskers are used instead of the whisker-modified compounding agent.

[0091] The product performance tests of Examples 1-3 and Comparative Examples 1-6 are as follows:

[0092]

[0093] It can be seen from Examples 1-3 and Comparative Examples 1-6 that the touch and abrasion resistance in Example 3 of the present invention have excellent effects. The maximum abrasion resistance can reach 2,625 revolutions. The touch and abrasion resistance can be improved in a coordinated manner;

[0094] When one of the chitosan-regulated yttrium oxide modifier and the whisker-modified compounding agent is not added to the product, the performance of the product deteriorates significantly. Only by coordinating the two and working together synergistically, the performance effect of the product is the most significant;

[0095] When yttrium oxide is used instead of pre-modified yttrium oxide in the preparation of chitosan-regulated yttrium oxide modifier, the chitosan compounding agent in the preparation of chitosan-regulated yttrium oxide modifier does not add a compounding agent, and lanthanum nitrate solution is not added in the preparation of the compounding agent, the performance of the product all shows a deteriorating trend. Only by using the chitosan compounding agent treated with the compounding agent and then optimizing the pre-modified yttrium oxide, the prepared chitosan-regulated yttrium oxide modifier has exclusivity, and the performance effect of the product is the most significant. Using other methods to replace it is not as effective as the present invention.

[0096] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
